Abstract
Description
Die Erfindung bezieht sich auf einen Kurvenförderer mit einem Endlosgurt, zwei zu seiner Umlenkung dienenden Walzen, einem Antriebsmittel, einer Führungseinrichtung mit daran ablaufenden Rollen und einem Gestell.The invention relates to a curved conveyor with an endless belt, two rollers serving to deflect it, a drive means, a guide device with rollers running thereon and a frame.
Kurvenförderer werden im Rahmen der automatisierten Produktion eingesetzt, falls sich aus räumlichen Gründen ein Veränderung der Transportrichtung um einen horizontalen Winkel als erforderlich erweist. In relativ einfach gestalteten Kurvenförderern finden konische, auf der Innenseite eines Endlosgurtes angeordnete Walzen Verwendung. Als nachteilig ist anzusehen, daß dem jeweiligen Umlenkwinkel angepaßte Walzen herzustellen sind, so daß keine rationelle Fertigung in hohen Stückzahlen möglich ist und sich die Gestehungskosten relativ hoch gestalten.Curved conveyors are used in the context of automated production if, for spatial reasons, a change in the transport direction by a horizontal angle proves to be necessary. Conical rollers arranged on the inside of an endless belt are used in curve conveyors of relatively simple design. It is to be regarded as a disadvantage that rolls adapted to the respective deflection angle have to be produced, so that no rational production in large numbers is possible and the production costs are relatively high.
Eine andere Möglichkeit besteht in der Montage von Ketten, die in der Nähe des Gurtrandes außerhalb, d.h. ober- und unterhalb des Endlosförderers umlaufen und über Mitnehmer mit dem Gurt verbunden sind. Aufgrund der mit zunehmender Benutzungsdauer unabdingbaren Längung der Kette erweist sich häufig eine kosten- und personalintensive Unterbrechung der Produktion und Reparatur als notwendig; weiterhin ist die zum Transport von Gegenständen verwendbare Gurtfläche durch die Kette entscheidend reduziert.Another possibility is to install chains that run outside the belt edge near the belt edge, ie above and below the endless conveyor and are connected to the belt by means of drivers. Due to the inevitable lengthening of the chain with increasing use, a costly and personnel-intensive interruption of production and repair often proves to be necessary; Furthermore, the belt area that can be used to transport objects is significantly reduced by the chain.
Aus der DE-OS 28 17 958 ist ein Kurvenförderer gattungsgemäßer Art bekannt, bei dem eine zum Antrieb dienende Kette in die Kurvenkrümmung bestimmenden Führungsschienen angeordnet und ebenfalls über Mitnehmer mit dem Endlosgurt verbunden ist. Zur Vergrößerung der maximal möglichen Transportgeschwindigkeit sind an den Mitnehmern Rollen montiert, die an den Führungsschienen ablaufen. Der Nachteil besteht darin, daß sich aufgrund der starren Fixierung der Rollen am Gurt eine hohe Präzision der Führungsschienen als notwendig erweist und daß ein Atmen des Endlosförderers, d.h. Ausgleich eventueller Toleranzen, Verformungen oder Belastungen nicht möglich ist.From DE-OS 28 17 958 a curved conveyor of the generic type is known, in which a chain serving to drive the drive is arranged in the curvature-determining guide rails and is also connected to the endless belt via drivers. To increase the maximum possible transport speed, rollers are mounted on the drivers, which run on the guide rails. The disadvantage is that due to the rigid fixation of the rollers to the belt, a high precision of the guide rails proves to be necessary and that breathing of the endless conveyor, i.e. Compensation for any tolerances, deformations or loads is not possible.
Ausgehend vom Stande der Technik liegt der Erfindung das Problem zugrunde, einen Kurvenförderer zu schaffen, der sich durch lange Lebensdauer, hohe Transportgeschwindigkeit und -kapazität sowie Preiswürdigkeit auszeichnet.Starting from the state of the art, the invention is based on the problem of creating a curved conveyor which is distinguished by a long service life, high transport speed and capacity, and value for money.
Erfindungsgemäß wird das Problem dadurch gelöst, daß das Antriebsmittel ein auf der Innenseite des Endlosgurtes befestigter Zahnriemen ist, die Walzen mit jeweils einem Zahnring versehen sind, der mit dem Zahnriemen im Eingriff steht, die Führungseinrichtung ein im konstanten Abstand zum Zahnriemen verlaufender, am Endlosgurt fixierter Profilgurt ist und daß die Rollen am Gestell um eine parallel zur Oberflächennormale des Endlosgurts verlaufende Achse drehbar befestigt und mit einer radial nach außen gerichteten Kraft beaufschlagt sind.According to the invention, the problem is solved in that the drive means is a toothed belt fastened to the inside of the endless belt, the rollers are each provided with a toothed ring which is in engagement with the toothed belt, the guide device is fixed to the endless belt and runs at a constant distance from the toothed belt Profile belt and that the rollers are rotatably attached to the frame about an axis parallel to the surface normal of the endless belt and are acted upon by a radially outward force.
Der Kerngedanke der Erfindung besteht darin, die zur Führung und zum Antrieb des Endlosgurtes dienenden Elemente auf seiner Innenseite anzuordnen. Die Übertragung des Antriebsmoments auf den Endlosgurt erfolgt durch einen auf seiner Innenseite befestigten, in konstanter Entfernung von seiner Berandung umlaufenden Zahnriemen. Die stirnseitig positionierten, zur Umlenkung des Endlosgurtes um jeweils 180° dienenden Walzen sind mit je einem im Eingriff mit dem Zahnriemen stehenden Zahnring versehen, der eine Drehmomentübertragung von der Walze auf den Gurt oder in umgekehrter Richtung ermöglicht. Der Antrieb kann durch eine der Walzen oder ein an beliebiger Position montiertes, in den Zahnriemen eingreifendes Zahnrad erfolgen, wobei eine geschützte Anbringung zwischen den Trums des Endlosgurtes bevorzugt ist. Zur Übertragung der nach innen gerichteten, auf den Endlosgurt als Folge seiner in radialer Richtung variierenden Geschwindigkeit wirkenden Kräfte auf das stationäre, den gesamten Kurvenförderer tragende Gestell ist eine Führungseinrichtung vorgesehen, die aus einem in konstantem Abstand vom Zahnriemen - und somit von der Berandung des Endlosgurts -fixierten, umlaufenden Profilgurt und daran ablaufenden, vorzugsweise äquidistant über die Kurve verteilten Rollen aufgebaut ist. Die Rollen sind um eine parallel zur Oberflächennormalen des Endlosgurtes verlaufende Achse drehbar am Gestell gelagert und, damit sie eventuellen Toleranzen, Belastungen und Verformungen selbsttätig ausweichen können, mit einer radial nach außen wirkenden Kraft, vorzugsweise einer Federkraft beaufschlagt. Eine weitere Aufgabe der Führungseinrichtung besteht darin, die vertikalen, durch das Transportgut bedingten Belastungen vom Endlosgurt auf das Gestell zu übertragen.The main idea of the invention is to arrange the elements for guiding and driving the endless belt on its inside. The drive torque is transmitted to the endless belt by means of a toothed belt attached to its inside and rotating at a constant distance from its edge. The rollers, which are positioned at the end and serve to deflect the endless belt by 180 ° in each case, are each provided with a toothed ring which is in engagement with the toothed belt and which enables torque transmission from the roller to the belt or in the opposite direction. The drive can take place by means of one of the rollers or a gearwheel mounted at any position and engaging in the toothed belt, with a protected attachment between the runs of the endless belt being preferred. A guide device is provided to transmit the inwardly directed forces acting on the endless belt as a result of its speed, which varies in the radial direction, to the stationary frame, which carries the entire curve conveyor, and which consists of a constant distance from the toothed belt - and thus from the edges of the endless belt -fixed, circumferential profile belt and rollers running thereon, preferably distributed equidistantly over the curve. The rollers are rotatably mounted on the frame about an axis parallel to the surface normal of the endless belt and, in order that they can automatically avoid tolerances, loads and deformations, are subjected to a radially outward force, preferably a spring force. Another job of The guide device consists of transferring the vertical loads caused by the goods to be transported from the endless belt to the frame.
Die Vorteile der Erfindung bestehen vornehmlich darin, daß die gesamte Gurtbreite, aufgrund der Tatsache, daß die Antriebs- und Führungselemente zwischen dem hin- und rücklaufenden Trum positioniert sind, als Förderbreite zur Verfügung steht, wobei auch Gegenstände mit Überbreite, also die Gurtbreite überschreitenden lateralen Abmessungen transportierbar sind. Die Verwendung eines Zahnriemens erlaubt, auf bewegte metallische Teile zu verzichten, so daß die Laufruhe und erzielbare Transportgeschwindigkeit gegenüber bekannten Kurvenförderern entscheidend gesteigert werden kann. Eine Reparatur und/oder ein Austausch defekter Antriebselemente ist nach einer Entfernung des Endlosgurtes unschwer möglich. Kommt ein Zahnriemen ohne Verstärkungsfasern zum Einsatz, tritt die mit zunehmender Benutzungsdauer unweigerlich auftretende Längung bei Endlosgurt und Zahnriemen in näherungsweise gleichem Maße auf; ein durch unterschiedliche Längung bedingtes Ablösen kann somit leicht unterbunden werden. Schließlich ist anzumerken, daß sich wegen der formschlüssigen Antriebsmomentübertragung auf den Zahnriemen erübrigt, den Endlosgurt oder den Zahnriemen zu spannen, so daß keine übermäßige Längung und unnötige Reduzierung der Lebensdauer des Kurvenförderers zu befürchten ist.The advantages of the invention consist primarily in the fact that the entire belt width, due to the fact that the drive and guide elements are positioned between the back and forth run, is available as the conveying width, and objects with an excess width, that is to say the lateral width exceeding the belt width, are also available Dimensions are transportable. The use of a toothed belt allows moving metal parts to be dispensed with, so that the smoothness and achievable transport speed can be increased significantly compared to known curved conveyors. A repair and / or replacement of defective drive elements is easily possible after the endless belt has been removed. If a toothed belt without reinforcing fibers is used, the elongation which inevitably occurs with the length of use of the endless belt and toothed belt occurs to approximately the same extent; detachment due to different elongation can thus be easily prevented. Finally, it should be noted that the positive drive torque transmission to the toothed belt makes it unnecessary to tension the endless belt or the toothed belt, so that there is no fear of excessive elongation and unnecessary reduction in the lifespan of the curved conveyor.
Kommen wälz-, d.h. kugel-, rollen- oder nadelgelagerte Rollen zum Einsatz, können die in radialer und vertikaler Richtung verlaufenden, vom Profilgurt auf die Rollen übertragenen Kräfte ohne unnötige Reibung und Geräusche auf das Gestell weitergeleitet werden.Come rolling, ie ball, roller or needle bearing If rollers are used, the forces that run in the radial and vertical directions and are transmitted from the profile belt to the rollers can be transmitted to the frame without unnecessary friction and noise.
Die Form der stirnseitig am Kurvenförderer gelagerten, den Endlosgurt umlenkenden Walzen ist im Rahmen des erfindungsgemäßen Gedankens beliebig. Eine konische Dimensionierung erlaubt zwar die Verwendung einteiliger Walzen; als nachteilig ist jedoch anzusehen, daß ihre Konizität in unmittelbarem Zusammenhang mit der Krümmung des Kurvenförderers steht und daß somit keine standardisierte, preisgünstige Produktion möglich ist. Bei alternativ einzusetzenden, zylindrischen Walzen ist zu berücksichtigen, daß die Geschwindigkeit des an ihnen anliegenden Endlosgurtes mit der (auf die Walze bezogen) axialen Position variiert, so daß die Walzen zur Unterbindung des als Folge der Friktion entstehenden Abriebs axial in separat drehbar gelagerte Abschnitte zu unterteilen ist.The shape of the rollers mounted on the end face of the curve conveyor and deflecting the endless belt is arbitrary within the scope of the inventive idea. A conical dimensioning allows the use of one-piece rollers; A disadvantage, however, is that their taper is directly related to the curvature of the curved conveyor and that therefore no standardized, inexpensive production is possible. In the case of cylindrical rollers which can be used alternatively, it must be taken into account that the speed of the endless belt adjoining them varies with the axial position (based on the roller), so that the rollers axially into sections which can be rotated separately to prevent the abrasion arising as a result of the friction divide it.
Aufgrund der leichten und schnellen Fertigung ist empfehlenswert, den Zahnriemen und/oder den Profilgurt auf den Endlosgurt aufzukleben. Falls geeignete Klebstoffe Verwendung finden, ist die Belastbarkeit mit einer Löt- oder Schweißverbindung vergleichbar. Ungeachtet dessen käme auch eine Schweiß- oder Nahtverbindung zusätzlich oder als Alternative in Betracht.Due to the easy and fast production, it is recommended to stick the toothed belt and / or the profile belt onto the endless belt. If suitable adhesives are used, the resilience is comparable to a soldered or welded connection. Regardless of this, a weld or seam connection could also be considered in addition or as an alternative.
Im speziellen ist eine Montage des Zahnriemens in der Nähe des radial äußeren Randes des Endlosgurtes bevorzugt, da sich zum einen der Abrieb wegen der Länge des Zahnriemens auf eine hohe Anzahl von Zähnen verteilt und die Lebensdauer somit verlängert ist, zum anderen auf den Endlosgurt keine durch das Antriebsmoment bedingten, radial nach innen gerichteten Stauchungskräfte wirken.In particular, the timing belt is mounted in the vicinity of the radially outer edge of the endless belt is preferred, because on the one hand the abrasion is distributed over a large number of teeth due to the length of the toothed belt and the service life is thus extended, and on the other hand no radially inward direction on the endless belt due to the drive torque Compression forces act.
Zahnriemen sind zur Aufnahme der Zugbelastungen mit Verstärkungen, z.B. aus Stahl oder Kevlar versehen. Da die Übertragung der Zugkräfte über den Gurt möglich ist und erfolgt, kann der Zahnriemen frei von Verstärkungen bleiben. Er wird somit preisgünstiger herstellbar.Toothed belts are used to absorb tensile loads with reinforcements, e.g. made of steel or kevlar. Since the transmission of the tensile forces via the belt is possible and takes place, the toothed belt can remain free of reinforcements. It is therefore cheaper to manufacture.
Der Querschnitt des Profilgurts wird vorteilhafterweise T-, U- oder winkelförmig gewählt. Der Vorteil besteht darin, daß auch größere vertikale und radial nach innen gerichtete Kräfte durch die formschlüssige Verbindung auf die Rollen übertragen werden können. Bei der konkreten Dimensionierung ist zu berücksichtigen, daß kleine Walzenradien nur bei Profilgurten mit geringer Stärke verwendbar sind.The cross section of the profile belt is advantageously chosen to be T, U or angular. The advantage is that even larger vertical and radially inward forces can be transmitted to the rollers through the positive connection. When dimensioning the concrete, it must be taken into account that small roller radii can only be used with low-profile tread belts.
Um nur noch einen einzigen Riemen auf den Endlosgurt aufbringen zu müssen, bietet sich an, ein Profil in die radial innere Flanke des Zahnriemens einzubringen und als Profilgurt einzusetzen.In order to only have to attach a single belt to the endless belt, it is advisable to insert a profile in the radially inner flank of the toothed belt and to use it as a profile belt.
Zum Antrieb des Zahnriemens ist im konkreten ein Doppelzahnriemen empfohlen, dessen innere Zahnreihe mit zwei im Abstand voneinander montierten Zahnrädern mit parallelen Achsen im Eingriff steht. Das Antriebsmoment wirkt auf eines der Zahnräder und wird durch einen Trum des Doppelzahnriemens, der näherungsweise parallel zur Tangente des Zahnriemens verläuft, auf letzteren übertragen. Wegen der durch die Krümmung des Endlosgurtes bedingten Biegung des Zahnriemens weisen benachbarte Zähne einen in Bewegungsrichtung nach außen ansteigenden relativen Abstand und/oder Breite auf. Die Zähne des Doppelzahnriemens verlaufen hingegen orthogonal zur Tangente und sind nicht gekrümmt. Als Vorzug ist anzusehen, daß der Antrieb an einer beliebigen Position zwischen dem hin- und rücklaufenden Trum des Endlosgurtes montierbar ist.In particular, a double toothed belt is recommended for driving the toothed belt, the inner row of teeth with two toothed wheels mounted at a distance from one another is engaged with parallel axes. The drive torque acts on one of the toothed wheels and is transmitted to the latter by a strand of the double toothed belt that runs approximately parallel to the tangent of the toothed belt. Because of the curvature of the toothed belt caused by the curvature of the endless belt, adjacent teeth have a relative distance and / or width that increases outward in the direction of movement. The teeth of the double toothed belt, on the other hand, are orthogonal to the tangent and are not curved. As an advantage it can be seen that the drive can be mounted at any position between the back and forth run of the endless belt.
